    What about respiratory protection? Just as important as eye protection. Also run grinder oriented going off edge of metal. His method of going onto the edge can catch and damage the disk. You need to realize some people watching these videos need all instructions to be correct not just vague recommendations.

    Do you have a prt number & where you purchased the rust buster wheel on the grinder in the video?.

    Please leave a product number of tools used on clips. Where to get RustBuster and product number used in this clip? I hate mill scale removal!

    In terms of surface preparation for welding, does sandblasting adequately prepare the metal to weld? I know that “metal in white”, freshly blasted metal, is usually ready for priming and painting, but should I grind the welding surfaces after pieces come out of my blast cabinet? Thanks, Tim
